Abstract:	Purpose – The purpose of this paper is to describe a novel, nanomaterial-based X-ray imaging technology, developed at the University of North Carolina. Design/methodology/approach – The paper describes a unique X-ray source, based on field emission from a carbon nanotube (CNT) cold cathode and discusses its application to computer tomography (CT). Findings – CNT-based X-ray sources are shown to offer improved performance over conventional thermionic devices and allow the design of gantry-free, stationary CT systems with faster scanning speeds and better image quality. The field emission technology has been commercialised by Xintek and a joint venture with Siemens, XinRay Systems, aims to commercialise CT imagers based on the technology. Originality/value – The paper describes a novel approach to the generation of X-rays and its use in medical CT imaging systems.
